We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

R00Activity Code Description: To support the second phase of a Career/Research Transition award program that provides 1 -3 years of independent research support (R00) contingent on securing an independent research position. Award recipients will be expected to compete successfully for independent R01 support from the NIH during the R00 research transition award period. |
Dissecting Serotonergic and Dopaminergic Contributions to the Neural Circuits Underlying Impulsive Behavior
Project Summary The parent R00 grant is focused on impulsive behavior which is characterized as acting without forethought and lacking the ability to withold responses. Disordered impulsivity is a major feature of a number of psychiatric disorders including attention deficit hyperactivity disorder (ADHD), conduct disorder, and antisocial personality disorder, as well as binge eating and manic episodes in bipolar disorders. Pharmacological treatments for impulsive behavior are inadequate, and a limiting factor in the development of new pharmacological treatments is a lack of understanding of the neural circuits underlying impulsivity. In previous work we identified a role for the serotonin 1B (5-HT1B) receptor in the modulation of impulsivity, and the research in the parent R00 grant is focused on understanding the circuit-level mechanisms through which this occurs. One set of studies used in vivo calcium imaging to assess the effect of 5-HT1B on cellular correlates of impulsive behavior. This administrative supplement proposes to build dynamic and predictive Bayesian models of the cellular encoding of impulsive behavior, using data collected in the R00, in order to better understand how neural activity patterns subserve impulsivity. Specifically we will address how the neural encoding is stable across days, how it changes in states of pathological impulsivity, and how it is shared across multiple subjects. Overall, this project will contribute to a better understanding of the neural basis of disordered impulsivity and inform targets for the development of new treatments for psychiatric disorders in which impulsivity is a key component.
